Understanding Drum and Disc Brakes: A Comprehensive Guide
Drum Brakes
Drum brakes utilize friction against the inner surface of a drum attached to the wheel. Each drum houses brake shoes lined with friction material and held in place by springs. When the brakes are applied, the shoes press against the drum, creating friction and slowing the vehicle.
Adjustment in Drum Brake Systems
As brake shoes wear down, the distance between them and the drum increases, leading to reduced braking efficiency. To counteract this, drum brakes require periodic adjustment to

Production of Compressed Air
Compressors
A compressor is a device that increases air pressure by reducing its volume. There are various types of compressors, each with its own operating principles and applications:
- Reciprocating Compressors: These compressors use pistons to compress air. They can be single-stage or dual-stage, with dual-stage compressors achieving higher pressures. Diaphragm compressors are a type of reciprocating compressor that uses a membrane to separate the air from the piston,

Explain application transport method in brief.
Application transport methods refer to the mechanisms used to facilitate the exchange of data between different software applications over a network. These methods ensure that data is transferred reliably and efficiently, regardless of the underlying network infrastructure.
One common application transport method is the Transmission Control Protocol (TCP), which provides reliable, connection-oriented communication between applications. TCP ensures that
